Re: Which winch?
How old are your winches? Are they self tailers? I've had winches up to 40 years old and they weren't "worn out" - they just needed servicing and a few springs & pawls. I've never even had to replace a bearing, let alone a gear.
I've never seen a winch wear out, only fail from misuse and/or abuse.
If you have to go for store bought new, I'd go for S/S Andersens, no question.
I haven't used Harkens but the current Lewmars are only "easy to service" in that they don't require a tool to get the drum lock nut off - they are a sort of thumb screw with a head somewhat like those "security" screws they use to assemble public restroom stalls, only a lot bigger.
I, myself, personally intend to continue being outspoken and opinionated, intolerant of all fanatics, fools and ignoramuses, deeply suspicious of all those who have "found the answer" and on my bad days, downright rude.
